Enum InstSameRegHint 

#[repr(u8)]
pub enum InstSameRegHint {
    None = 0,
    RO = 1,
    WO = 2,
}

Hint used when two or more operands of an instruction are the same register.

Influences the RW operations query: instructions such as xor x, x produce write-only semantics, and x, x read-only.

Variants

None = 0

No special handling.

RO = 1

Operands become read-only, the operation doesn’t change the content (X & X and similar).

WO = 2

Operands become write-only, the content of the input(s) doesn’t matter (X ^ X, X - X, and similar).
